Targeted Photodynamic Therapy Shown Highly Effective Against Prostate Cancer

June 20, 2017

Researchers presenting a preclinical study at the 2017 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) demonstrated the efficacy and optimal dose for targeted photodynamic therapy (tPDT) to treat prostate cancer before and during surgery. Prostate-specific membrane antigen (PSMA) was targeted with an anti-PSMA antibody radiolabeled with the tracer indium-111 (111In) and coupled with specialized photosensitizers that cause cell destruction upon exposure to near-infrared (NIR). The combined formula is 111In-DTPA-D2B-IRDye700DX.
